"There are no limits to what you can accomplish, except the limits 

you place on your own thinking."

Brian Tracy

There are no limits on what you can do in this life, everything and every goal is limitless and attainable as long as you work hard for it. Strive to do your best and work hard towards your goals because they mean something. You can do anything you want in this life as long as you put yourself to the test, Push yourself harder, and believe in yourself. If you believe in yourself and work hard and do your best to achieve these goals. Then you will be successful, but only if you believe in yourself and put work in. When you "kinda" hard and you "kinda" believe in yourself you're limiting yourself from the success you are able to attain.The moment you start doubting yourself in any goal you have, academic or not , you're limiting yourself from success. You are what stops yourself from accomplishing what you want to accomplish. You are what makes yourself accomplish what you want to accomplish in life. Strive for success, and believe in yourself all the way, don't put limits to your success.
